Abstract

A double-spiral lipstick tube that is small-sized but can accommodate a standard volume of a paste body product. The double-spiral lipstick includes a tube body that houses an outer screw member and an inner screw member embedded inside the outer screw member. The double-spiral lipstick also includes a middle segment that is axially fixed to and circumferentially slidable relative to the outer screw member. The double-spiral lipstick further includes a bead having a barrel body for housing the paste body. A lower portion of the bead extends into the inner portion of the inner screw member. The rotation of the tube body causes rotation of the outer screw member and the inner screw member, which in turn pushes the bead and the inner screw member to move up together up to a certain distance, and thereafter on a continuous rotation of the tube body, only the bead moves up.
